摘　　要：为了研究公路工程盐渍土易溶盐合理的测定方法,对典型区域的盐渍土进行了颗粒组成统计分析、粗粒盐渍土试样制备粒径研究以及土水比与含盐量关系的分析。结果表明:砾类土易溶盐试验采用通过5 mm筛孔的烘干土样300 g,砂类土易溶盐试验采用通过1 mm筛孔的烘干土样300 g,细粒土易溶盐试验采用通过1 mm筛孔的烘干土样100 g,土水比1∶5进行易溶盐离子试验,测定的易溶盐含量具有较好的代表性,符合工程实际。In order to study reasonable test methods for soluble salt in saline soil in highway engineering,the statistical analysis of particle composition in the typical region,the research on preparation particle diameter of coarse grained saline soil and the analysis on relation between soil-water ratio and salt content are performed.The results show that the test method for soluble salt in gravel saline soil using drying soil samples of 300 g which pass 5 mm mesh,the test method for soluble salt in sand saline soil using drying soil samples of 300 g which pass 1 mm mesh as well as the test method for soluble salt in fine grained saline soil using drying soil samples of 100 g which pass 1 mm mesh are representative,and they agree with the actual situations.
